In order to collect data we used medical histories of children with respiratory infections. Incidence of respiratory infections in children in war period was 230/1000, while in post-war period it was 190/1000. There was no significant difference in the incidence of respiratory infections in children during war and after the war (p=0.051). e have not found increase in respiratory infections prevalence in children treated during war period at the Pediatric department of University Hospital Mostar, compared to the period after the war. However, we did report certain differences related to age, clinical parameters, seasonal pattern, diagnosis, therapy and mean hospitalization time. Key words: respiratory infections, children, incidence, war, Bosnia and Herzegovina Introduction Patients with acute respiratory infections, especially those with infections of upper respiratory tract, are the most common visitors of pediatric departments and other primary health care practices. They are the reason for frequent antibiotic prescription and the main reason for missing from school 1,2. The children are more sensitive to respiratory infects than adults. The reason for this could be the first contact and inefficient specific immunization to microbes in early childhood 3. The most common respiratory microbes are viruses, Mycoplasma and bacteria. The viruses are the main cause for more then 85% of all acute respiratory infections 4. Clinically, these infections appear within whole spectrum of symptoms and different stages of illness. Respiratory infections can be divided into infections of upper and lower respiratory tract. The infections are usually mild catharal infections of upper respiratory tract caused by viruses and their complications as bacterial superinfections (sinusitis, otitis). Upper respiratory infections are angina and croup syndrome, and they appear in several well-defined diseases which include laryngeal diphtheria, acute catarrhal and spastic laryngitis and malignant obstructive laryngotracheobronchitis. Acute respiratory infections of lower respiratory tract are acute bronchitis, bronchiolitis and pneumonia 5. Pneumonia is the most difficult infection of the respiratory tract and requests special treatment, although it is involved in only 1% of all acute respiratory infections 5. 95% of all pneumonias in small children in world appear in developing countries, such as Bosnia and Herzegovina. Etiological diagnosis of respiratory infections is rarely established in developing countries, therefore orld Health Organization (HO) recommends primary healthcare physicians to make a diagnose on the basis of clinical parameters. HO suggests appropriate treatment of respiratory infections which will develop health care and decrease the mortality 6. The awareness of rational antibiotics prescription often lacks in reference to acute infections of the upper respiratory tract, which then leads to unnecessary use of antibiotics in treatment of viral respiratory infections 7,8. 70% of all per oral antimicrobial drugs are used for treat- Received for publication March 13, 2009 49
ment of acute respiratory infections 4. Researches prove that the number of prescribed antibiotics annually increases with age and with years of physicians work experience 7,9. Irrational prescribing of antibiotics cause resistance of pathogenic microorganisms which may cause epidemics or even pandemic measures in future, and today it is already a significant problem in the world 7,10. Inflammatory mediators that are involved in acute respiratory infections during the development of the respiratory tract can leave long-term consequences on pulmonary functions 5,11,12. In the world, acute respiratory infections are the leading cause of mortality in children younger than 5 years old 5. Most of these deaths are caused by pneumonia and bronchiolitis 5,13. Stated facts imply that prevention of these infections in children is extremely important. Hygiene dietetic regime (hand washing and appropriate food) and separating sick children from healthy, if possible, lays the foundation of prevention of acute respiratory infections 3,14. The aim of this study was to show prevalence of acute respiratory infections in children treated at the University Hospital Mostar. Materials and Methods This cross-sectional study was performed at the Clinic for Pediatrics, University Hospital Mostar during two periods: during the war (1993 and 1994) and after the war (2003 and 2004). In war period the number of hospitalized children was 1107 and 273 children with acute respiratory infections were included in the study. In after the war period the number of hospitalized children was 2774 and 527 had respiratory infections and were included in the study. The data were obtained from medical histories of the children treated at the Department of Pediatrics, University Hospital Mostar. The used parameters were age, gender, blood examination (sedimentation of erythrocytes and leukocytes), body temperature, annual seasons and mean hospitalization time. In data evaluation C-reactive protein was excluded because it was not used during the war period. The data have been processed using the program SPSS 10.0 for indows and interpreted with descriptive statistics. For statistical analyses we used c²-test and F-test. The statistical significance for all tests was p<0.05. Results In this study it has been proven that there is no statistically significant difference in incidence of respiratory infections in children during war and after the war (Table 1). Number of upper respiratory infections per 1000 hospitalized children decreased in post-war period but the number of lower respiratory infections did not change (Table 1). Considering the age, children were divided in four groups: newborns (0 28 days), infants (1 12 months), little children (2 6 years) and school children (7 19 years). Number of newborns statistically decreased and number of little children with respiratory infections increased in post-war period (Table 2). There was no statistically significant gender difference in incidence of respiratory infections in children in these two periods (Table 3). The number of children with positive laboratory parameters (SE 11 mm/h, L 10 10 9 /L) increased in post-war period, while the number of febrile children (Tax 38 C) with respiratory infection remained the same two other periods (Table 4). Considering seasons, the number of children with respiratory infections has increased in winter and fall in period after the war (Table 5). The number of children with the diagnosis of angina, acute pharyngitis and acute bronchitis decreased, and those with diagnose of croup syndrome, bronchopneumonia and pleuropneumonia increased in period after war (Table 6). The number of children with respiratory infections treated with penicillins, cephalosporins and symptomatologic therapy increased in period after the war (Table 7). Mean hospitalization time increased in children with diagnose of acute rhinosinusitis, acute rhinopharyngitis and bronhopneumonia in period after the war (Table 8). Discussion and Conclusion Because of specific socioeconomic conditions increased incidence of respiratory infections in children was expected during the war. People of Mostar were fighting for existence and living conditions were minimal 15. Provision of adequate shelter, food, water and sanitation was TABLE 1 INCIDENCE OF RESPIRATORY INFECTIONS DURING AR AND PERIOD AFTER THE AR IN CHILDREN HOSPITALIZED AT THE CLINIC FOR PEDIATRICS OF THE UNIVERSITY HOSPITAL MOSTAR Hospitalized children (N) Children with respiratory infections N/1000 hospitalized Period Children with respiratory infections (N) URT LRT A URT LRT A ar 155 118 273 1187 131 99 230 After the war 220 307 527 2774 79* 111 190 URT upper respiratory tract; LRT lower respiratory tract; A all children with respiratory infections * c 2 =12.88; p<0.001 c 2 =0.69; p=0.408 c 2 =3.81; p=0.051 50

Other possible reasons for expecting increase in incidence of respiratory infections in children in the war are stress, overcrowding and malnutrition 6,14,16,18. Results of this research show that there was no statistically significant difference in incidence of respiratory infections of children during the war and after war period. These results are not in correlation with similar researches in world that show increased incidence of respiratory infections in children in war conditions 17,18. The number of newborns in post-war period decreased. Incidence of respiratory infections in little children increased in period after the war, and incidence in other age groups did not change. Respiratory infections were most frequent in little children which correlates with similar researches in Senegal, Asia and Latin America 19 21. No statistically significant difference was found between children in two periods in relation to gender, although respiratory infections were more frequent in boys which correlates with world data 22. In both periods respiratory infections in children were most frequent in winter which correlates with studies performed in Canada, North America and Russia 23 25. In this study it was found that number of children with acute tonsillopharyngitis, acute pharyngitis and acute bronchitis has decreased in the period after the war. Most probable reason was better organization and availability of primary health care, so that the children with this diagnosis were treated in primary health care. Incidence of children with diagnosis croup syndrome, bronchopneumonia and pleuropneumonia reached statistically significant increase in period after the war. e assume that the reason for this is better as well as available health care and diagnostic procedure. Fewer number of children was treated with penicillins during period after the war. Because of resistance, physicians all over the world prescribe new generations of antibiotics, for example cephalosporins. Maybe, this is the reason why incidence of children treated with cephalosporins in- TABLE 4 LABORATORY PARAMETERS IN CHILDREN ITH RESPIRATORY INFECTIONS Number (%) used clinical parameters S L T Period <11mm/h 11mm/h Did not measure <10 10 9 /L 10 10 9 /L <38 C 38 C ar 25 (9.2) 221 (81.0)* 27 (9.9) 63 (23.1) 210 (76.9) 123 (45.1) 150 (54.9) After war 86 (16.3) 398 (75.5)* 43 (8.2) 259 (49.1) 268 (50.9) 203 (38.5) 324 (61.5) All 111 (13.9) 619 (77.4) 70 (8.8) 322 (40.3) 478 (59.8) 326 (40.8) 474 (59.3) S sedimentation of erythrocytes; L leukocytes; T body temperature *c 2 =7.32; p=0.006 c 2 =50.82; p<0.001 c 2 =3.18; p=0.074 51

Awareness among doctors about the judicious use of antibiotics and patient education all over the world will reduce inappropriate use of antibiotics. Incidence of children treated only with symptomatic therapy increased in period after the war, therefore we can say that the Clinic for Pediatrics of the University Hospital Mostar is improving the trend of rational antibiotic prescribing. Mean hospitalization time of children with diagnosis of acute rhinosinusitis, rhinopharyngitis and bronchopneumonia decreased in the post- -war period. These results are opposite to those from study performed in Guinea where mean hospitalization time was shorter during armed conflict 18. Mean hospitalization time of children with respiratory infections is TABLE 7 TIONS ACCORDING TO THERAPY Therapy A Penicillins 202 (74.0) 320 (60.7)* Cephalosporins 15 (5.5) 72 (13.7) Aminoglycosides 9 (3.3) 5 (0.9) Macrolides and lincosamides 21 (7.7) 29 (5.5) Sulfonamides and trimethoprim 13 (4.8) 10 (1.9) Symptomatic therapy 13 (4.8) 91 (17.3) war period; A period after the war *c 2 =13.97; p<0.001 c 2 =37.35; p<0.001 c 2 =58.50; p<0.001 longer in war and after the war period than in the world. Mean hospitalization time for children with pneumonia in war period was 15.0±4.9 days, in period after the war 11.7±4.7 days and in the world 3 26 to 5 days 27. Mean hospitalization time for children with infections of lower respiratory tract was 9.3±3.7 to 15.0±4.9 days, while in similar study performed in Dallas, Texas, mean hospitalization time for children with infections of lower respiratory tract was 5 days 27. The most important conclusion of this study is that there was no statistically significant difference in incidence of respiratory infections in children during war and period after the war.

Obuhva}ene su dvije skupine djece s respiratornim infekcijama lije~ene na Odjelu za dje~je bolesti KB Mostar u razdoblju 1993. i 1994. godine te 2003. i 2004. godine. U cilju skupljanja podataka kori{tene su povijesti bolesti djece s respiratornim infekcijama lije~ene na Odjelu za dje~je bolesti KB Mostar. U~estalost respiratornih infekcija u djece u ratnom razdoblju je 230/1000, a u poslijeratnom razdoblju 190/1000 hospitaliziranih. Pokazalo se da nema statisti~ki zna~ajne razlike izme u navedenih skupina odnosno da nema zna~ajnog smanjenja broja bolesnika u poslijeratnom razdoblju (c 2 =3,810; p=0,051). Tijekom ratnog razdoblja nismo na{li ve}u zastupljenost respiratornih infekcija u djece lije~ene na Odjelu za dje~je bolesti KB Mostar u odnosu na poslijeratno razdoblje. Uspore uju}i promatrana razdoblja utvrdili smo odre ene razlike u djece s respiratornim infekcijama s obzirom na dob, klini~ke parametre, godi{nja doba, dijagnozu, lije~enje i duljinu boravka u bolnici. 53
